This week, we had experts coming to our classroom. They were David and Mr. Niznik. They came because we invited them to look at our Contraption Projects that we have been working on for one week. They came on a Tuesday afternoon. Our project was called the paintanater. That was because a stone will be painted by our system. Mr.Niznik and David were assessing our design. We were divided in groups of 2. We had to bring materials from home, so we brought wood, string, paint, stones, paper, a car, a book, and a brick. We’ve had problems with the pulley, but we found and worked out some solutions.
